Letters Patent No. 114,463, dated May 2, 1871.

lMPROVEMENT IN GRAIN-SEPARATING AND CLEANING ATTACHMENTS-TO THRASHING-MACHINES.

The :schedule referred to in these Letters Patent and making part of thesame.

To It'll whom it may concern it was necessary to put an extra pulley onthe cylinder-shaft to drive the fan, and an extra shaft on thethrasher-frame to work the shaker.

Tbe'object of my invention is so to construct the separator and cleanerthat they may be attached to the old-fashioned thrashers withoutaltering the thrashers; and

My improvement consists in a novel combination of mechanism, hereinafterspecified, for driving'both the fan and the separator from a cross-shafton the separator-fi-ame.

In the accompanying drawing- Figure l is a plan, and

Figure 2 an elevation of my improved attachment.

A frame, A, supports a fan, B, and a shakingscreeu, O.

The construction of the separating devices is well known and needs nodescription.

To carry out niy improvement I mount a crossshaft, D, in suitablehearings in the frame.

This shaft is driven by a band, (i, from a pulley on thethrashing-cylinder, which baud encircles a pulley, D, on the shaft.

The fan is driven by a band, 0, encircling a pulley, E, on the sameshaft D, but at-the end opposite that on which the pulley D is mounted.

The shaker O is vibrated by pitmen F F driven by cranks or crank-pins fon shaft D.

By this arrangement all the separating and cleaning mechanism is drivenfrom the shaft D, and as the shaker is driven from both ends of saidshaft the strain is less and the motion more uniform than if driven fromone end only.

My improved attachment can be secured to the thrasber by hooks, and isdriven by a band from the pulley, which usually would drive the fan.

I do not, broadly, claim driving a separator and cleaner from across-shaft; neither do I claim, broadly, the combination of a separatorand a cleaner.

I claim as my invention-- The separating and cleaning attachment forthrashers herein described, consisting of the frame A, the separator O,the cleaner, the cross-shaft D, the two pi'tmen F for driving theshaker, the pulley E on the cross-shaft, and the fan, all these partsbeing combined, constructed, and arranged as described for jointoperation.

In testimony whereof I have hereunto subscribed my name.
